Failed Attempts at Peace

I am extremely upset right now.  Woke up upset, had a bad day, yatta yatta.

I know that when I'm upset, I yell.  I don't mean to, I don't even notice that I do until my dad yells at me for it.  He does the same thing (despite being in denial about it).  He also doesn't like it when I yell, and I don't like it when he yells.

Therefore, I decided to try talking indirectly to him since everyone in the family now texts.  Idk, I guess I was hoping to get through a conversation explaining why I don't want them barging into my room asking me things and yelling at me when I yell at them.  Unfortunately, I guess my dad didn't share the same sentiments.

I texted Dad saying, "I don't want to come out of my room or talk directly to anyone right now because I am upset.  Is that okay?"

Unfortunately, Dad then decides that with this text, it'd be perfectly okay to walk right into my room to ask me why I am upset.  I tell him I don't want to yell at him, and if he could just talk to me indirectly, like with text or something.  He asks me again. I tell him I don't want to yell.  He keeps asking. Eventually, he gets frustrated at my lack of answers and leaves, telling me I can go starve for all he cares.

Okay. Thank you.
I tried, I guess.
